Description
The present invention relates to a kind of pharmaceutical synthesis plant, more particularly, relates to N, Ν'-nickel di-n-butyldithiocarbamate production plant.
GENERAL BACKGROUND
N, Ν'-nickel di-n-butyldithiocarbamate is mainly used as a light stabilizer and antiozonant for polymer materials. It has very good light stability in polypropylene fiber, film and narrow band. The dosage is 0.3-0.5 parts. In butyl benzene, chloroprene, chlorosulfonated polyethylene and other synthetic rubbers, it has the role of preventing solar cracking and ozone cracking, as well as improving the heat resistance of chloroprene rubber and chlorosulfonated polyethylene. Most of the existing production plant processes are complex. Thus, as a light stabilizer, the advantages and disadvantages of production equipment of N, N'-nickel di-n-butyldithiocarbamate have a great economic significant for improving product quality and reducing the by-product contents.
SUMMARY
The purpose of the present invention is to provide N, N'-nickel di-n-butyldithiocarbamate production plant, including: reactor (D101), filter (LI01), scrubber (LI02), dryer (LI03), tank (F101, Fl02), pump (J101, JI02); among them, pump (JI01) is connected respectively to tank (Fl01) and reactor (D101), scrubber (LI02) is connected respectively to filter (L101) and dryer (LI03); among them, nominal volume of reactor (D101) is 1100-1200 L, full volume of tank (F101) is 4.2-4.3 m3, inlet diameter of pump (J101) is 160-165 mm.
N, N'-nickel di-n-butyldithiocarbamate production plant, the production process is: added dibutylamine, carbon disulfide and caustic soda into reactor D101 according to the ratio, stirred and reacted at 30-36 °C for 70-90 min, generated sodium dibutyldithiocarbamate solution. Added nickel chloride solution with a mass fraction of 30-40% into sodium dibutyldithiocarbamate solution, carried out the metathesis
2018101995 06 Dec 2018 reaction at 20-25 °C for 2-3 h under stirring. The crude reaction product is precipitated as solid. Filtered, washed and dried the crude product by L101, L102 and LI 03, and obtained the finished product. The advantages of this invention are that the reaction time is reduced and the reaction rate is improved.
